This research aims at identifying elements that might create an enabling environment for the protection of human security in Canada’s Arctic communities. Human security aims at protecting individual(s) against physical or non-physical, violent or non-violent threats (environment, health, development or well-being). In order to assess the current human security in Canadian Arctic, this research analyses the relational dynamics within Canadian Rangers patrols, which are composed of Indigenous people under the responsibility of non-Indigenous instructors. It focuses on Nunavik, where communities suffer from many risks related to the concept of human security, and analyses a corpus of 21 qualitative interviews and field observations conducted in 2016 and 2017. Data interpretation reveals that the Canadian government indirectly strengthens human security of its Arctic communities through Canadian Rangers and Junior Canadian Rangers patrols - Canadian Rangers’ youth counterpart. This strengthening of human security in Canadian Arctic communities results from a three-step process based on balanced and respectful relationship dynamics between Inuit Rangers and non-Inuit instructors, allowing Canadian Rangers patrols and Junior Canadian Rangers patrols to act as a source and a guarantee of human security.
